LATCHING DEVICE 'Fon WINDOW'WINGS, noo'ns, AND THE LIKE.

' Application-filed Septinbe To all whom it may concern..-

lie it known that I, HANK citizen of the State Germany, residing at Sind'elfingen, WVurttemberg; GermanyyZiS Bahnhofstinsse, have 'invented' certain new and useful Improve inents in a Latching Device for i indow ings, Doors, and the like, of which the following is a specification.

This invention relates to A device for 3 latching Window-Wings, doors, and the like, Which'latching device iseonst'ructedflin such a manner that it isactuated'automatically, when the windowwving or door etc. is either closed or opened, and thereby adjusted to and from its operative position and vice versa.

The gist of the invention resides in providing av latching meansvproper of two or' more elements'whieh are staggered in such relation to each other that, when the the latching post tion, one of said elementswilhbelocated'hetween the swinging vertical edgeof the door or Window-Wing and the other element will be located outside oi the door'or Wing in such a Way as 'to form an abutment therefor whereby the door 'or Window is latched in its closedposition. 'The two elementsjm'entioned are 'inovable horizontally, and are generally speaking moved' 'throughan angle of about ninety degrees. The elements referred to may be connected" with each other in such a manner that the movement of one of them is transmitted to the other, either in the 'same direction or in a reversedirection, according to the arrangement and combination of the connecting menrhers. The horizontally movable elements "are also vertically movable, and if the two elements move in the same-tlirection, the lengthsof their respective,- paths of movement may be equal or imequal.

One form: of construction ofthe i-nvention "ma consist, for instance, of two: or more coa'xialvertical shafts, or sections of; a shaft, carrying lateral arms" or the! like which ex tend. throughoblique? slots, 1 prouji' 11D}: rel.- etively [stationary -a rms or thev like; are-staggered;- genera-ll.

on its. pivots, theh the shaft will be correspondingly rotated in the same 'direction, -'butit'will also be lifted to" an extent corresponding to the inclination of the slot engaged by the 1 arm '01 that 'sh-a ft or shaft section. Simultaneously therewith, the other shafts-0r shaft sections will be rotated, as- Well as lifted, by their arms and the cooperatingslots, be thefa ct that the movement of the first shaft or Shaftsection istranslnitted t0 the other shaft or shaft section,- ivhereby the Wing, or the door; is latch-odor" release'dyaccording to the direction, of the movements.

If desired, those parts which hold fast the *door or the windoW-Wingunay cooperate ii'tha' guide slot, theinelinati'on of which is slightly l'essthanthe inclination of the guide' slot with which those parts which are moved by'the; door or the Wing cooperate;- the path of the partswhich abut against the door. or the Wing in such case is correspond- F ingly longer than. that of. the'other" movable members form ingpart of the locking device.

. Int-his way a very accurate and firm fitting of the door or window in its frame is attaiined', tegetheiiwvith a certain yieldingness, especially if the element which holds the --d'0or or window wing is provided with a resilient or an elastic linin'gor the-like. On the: Whole the latching device; isvery simple,

' and reliable in action.

'My invention is illustrated 'diagrainmm tically by Way of example in the accompanying drawing, in which: Fig. 1 is aperspectiveillustraton'of. a Window-Wingforming; part of: the-body of'a 'm'otor-car, the windowheingclosed; Fig.2 is a similar illustration, showing} the same 'Win'dowqving in an open; position; Fig.3 is'a detail perwspecti've' View: of the latching device prow'i-dedioir the stationarypart of the body at th iiight hendi of the Window-Wing end Fig. is ai1iiafntviW-'0ifi thisdevice;

One of the latter, f in the example shown, is connected with a spiral spring Zr which tends to turn the shaft in a certain direction, either so as to adjust the latching device to a closed position or so as to shift it to an open position. l essthan that of the slot It, so that when the parts are brought.- to the position shown in Fig. 1, the plate y will engage the wing or door under an increased pressure. The is to say, if the slots h and 71. are correspondingly inclined, the swinging movements of the plates 9 and y will be of equal extent and the wing or door (I, will be engaged by the plate r with perhaps only a slight pressure. If, however, the inclination of the slot h is less than that of the slot 72., then the adjustment of the plate 9 is such that it is pressed against the door or wing to greater extent. The object of this arrangement is to obtain a secure closure of the wing, or of the door respectively, if the wing or the door is capable of yielding to a certain extent with respect to the car body, etc. In such a case, the plates may be provided with a resilient cushion, as for instance a piece of rubber 1, Fig. 8, to permit the aforesaid adjustment of the plate g.

The position of the plates 9, g, in Fig. 8 corresponds to the position of the parts in Fig. 2 in which the window wing is open. The plate 5 projects in the direction of the wall, of the car body, and the other plate projects outwardly approximately at right angles thereto. The position of the plates is changed when the wing is closed, the plate 5 being then turned inwardly (Fig. 1) and the plate 9 being turned toward and over the door or wing so as to keep it closed. In other words, as the wing, door, or the like is moved from the closed position shown in Fig. l, toward'the open position of Fig. 2, the pressure exerted thereby upon the plate g will swing the latter and the plate 9 to the position shown in Fig. 2'; similarly as the wing, door or the like is closed the pressure exerted thereby upon the plate 9' will. adjust the latter and the plate back to the position illustrated in Fig. l.

in the latter position, the plate 9 is located between an edge of the wing, door or the like and a contiguous edge of the casing, body, or equivalent element and servesto press the plateg' against the wing, door or the like, over a face of which said plate 9 extends, to fix'said wing, door, or the like in its closed position. Owing to the fact that the slots h, h are inclined,the'shaft f,

f, is correspondinglylifted and the spring I 7a correspondingly compressed as the door. or wing .15 moved toward its closed position,

The inclination of the slot h may be hen the door is opened, the plates g, are moved back into the positions they occupy in Fig. 3 in which they are also retained by the spring 70 which is always under a certain tension.

I claim:
